The sample cannot be made to work
without modifications on Entity
Framework 6 since the latter
implements its own core APIs separate
from the .NET framework and contains
other breaking changes. We are
currently not actively developing this
sample and therefore we have no plans
to publish a new version compatible
with EF6.

That said, EF6 introduces a new
feature called Interception which can
help application and library
developers achieve most of the same
functionality without implementing a
wrapping EF provider. For more
information about Interception and
other new features in Entity Framework
6, refer to the EF documentation at
